Be it known that L loi-in W. Ni-urn7 a citizen ot the United States, anda resident of Detroit. county ot lVayne. and. iitate ot hlichigan, haveinvented certain new and useful Improvements in Pinion llflountings. otwhich the 'Following is a full., clear, conoise. and exact description,such as will enable others skilled in the art to which the inventionrelates to malte and use the seme, reference being made therein to theaccompanyingdrawings, which form a part of this speciication.

The invention relates to niountings 'toi' pinions and like members andmore particularly to a mounting haif'ing' special utility in anassemblage including a bevel pinion and a ringl gear as employed incertain types of automobile driving mechanism.

ln autom ohiles including in the iinal drive differential mechanism ofthe usual type it is import-ant to reduce as far as possible thedimensions of the differential housingI and thereby inerease road.clearance. ln this and similar situations where compactness is adesideii'atnin or Where an element.7 as. a pinion7 must be mounted uponthe end ot a shaft and especially when in close prox iniity to otherstructures, or Where this pinion is of relatively smalll diameter it isoften inconvenient to employ the usual forms of securing means.

The primary object Ot myinvention thereicoi'e is toprovide a securing`means whereby a pinion or the like may be mounted upon the extreme endot a shaft V\\" ithout requiring any parts that extend beyond or passthrough the pinion itself.

A. further object is to provide a mounting whereby pinion 0r the likemay be secured upon the end ot' a shaft and may be provided with abea-rino; in close i'noniinity to the Working surface. the near teeth.

A further object is to provide a pinion niouinin'g and supportingconstruction ot especial utility in connection with the drivn ini; meanstor the d' erential mechanism ot @ther objects and advantages willapixea r :trom the followingdescription taken in connection with theaccompanying drawings illustrating one embodiment ot my invention and inwhich Figure l is a plan view, partly in section, of a portion of thedriving mechanism of an automobile.
